Darren Rausch with the Greenfield Health Department checked the refrigerator to see how much flu vaccine supply they have left and liked what he saw Monday morning.

"There are seven unopened vials, which would be 70 doses," Rausch said. "The fact that we still have some available is kind of a happy accident for us. The fact that other players don't have any just means they used their supply in the fall, and they weren't anticipating the demand in January."

Rausch said he believes because last year's flu season was much less severe, many people didn't get vaccinated this fall at the Health Department, leaving plenty left over for the January rush.

Despite the increased demand, the Greenfield Health Department said it has enough to last through the season, but some area pharmacies are scrambling to get more, including several Walgreens.

The company told WISN 12 News that only about half of their stores in southeast Wisconsin are stocked, but they expected to receive more shipments Monday.

"This year, it's more along the lines of a major mountain, and we're still peaking, as far as we can tell," Rausch said of the number of flu cases.

While there's still time to get protected, experts expect another big rush next fall, when the vaccine is in high supply.

The Milwaukee and North Shore Health Departments told WISN 12 News they expect to have a reduced supply of the vaccine, but North Shore doesn't have any plans to order more.
